Find Min Max Difference
Learn this problemProblem statement
Given one unsorted array of size n and integer k.
From subsequences of size n-k, find the max of consecutive element dfferences in the sorted subsequences AND from these max differences return the min difference.
A subsequence is any combination of integers.
Function
findMinMaxDifference(arr: int[], k: int) → intExamples
Example 1
arr = [1, 4, 3, 6, 5]k = 2return = 1Example - [1,4,3,6,5], k = 2, n-k = 3
Some Possible subequences of size 3 :
[4,3,1] (sorted) -> [1,3,4]
Diffs : 4-3 = 1, 3-1 = 1. Max of these is 1
[1,6,4] (sorted) -> [1,4,6]
Diffs : 6-4 = 2, 4-1 = 3. Max of these is 3
[3,6,5] (sorted) -> [3,5,6]
Diffs : 6-5 = 1, 5-3 = 2. Max of these is 2
Other subsequences follow....
Out of all possible sequences, we get the max diff in each subsequence.
Out of these maxes find the minimum diff.
In our case it's 1.
